\label{ch:metodologia}

\section{Tipos de prueba}
\begin{enumerate}
  \item \textbf{Unitarias} --- pytest (agent y API bot).
  \item \textbf{Humo / funcional} --- curl y checks HTTP del gateway.
  \item \textbf{Carga} --- k6 perfil \texttt{shared8g}.
  \item \textbf{Capacidad} --- modelo anal\'itico (no carga de 100k PDFs).
\end{enumerate}

\section{Herramientas}
k6 (Grafana), pytest, Docker stats, curl, pdflatex/pgfplots.

\section{SLOs perfil \texttt{shared8g}}
\begin{itemize}
  \item Gateway \texttt{/health/live}: p95 $<$500\,ms; fail $<$1\,\%.
  \item Heartbeats bot: p95 $<$800\,ms; checks $>$95\,\%.
  \item No usar \texttt{/health} agregado como SLO de latencia.
\end{itemize}
